To all whom it may coztccrvz: I

Be it known that we, VERNON ROYLE and WILLIAM COCHRAN, citizens of theUnited States, and residents of Paterson, in thecounty of Passaic andState of New Jersey,

have invented a new and useful Improvement A practical embodiment of ourinvention isrepresented in the accompanying drawings, in which- Figure 1is a view of the machine in side elevation. Fig. 2 is a view of the samein op posite side elevation. Fig. 3 is a partial view in frontelevation. Fig. 4 is an enlarged partial vertical section from front torear in the plane of the line 4 a of Fig. 3. Figs. 5, 6, and 7 representenlarged detail views of the mechanism for feeding the chain of cards tobe punched. Figs. 8, 9, and 10 represent enlarged detail views of themeans for feeding the chain of pattern-cards in either of two oppositedirections and at different rates of speed. Fig. 11 is an enlarged viewin detail, showing the means for centering and retaining thepattern-cylinders accurately in position for action upon theselecting-needles.

Figs. 14, 15, and 16 are still further enlarged views of portionsof the patterncylinder, illustrating more clearly its structure. Figs.17,18, 19,and 20 represent views in detail of the structure of theselecting-needles with their removable tips; and Figs. 21 and 22represent parts of cards, the former representing what we are pleased toterm the positive pattern and the latter what we are pleased to term thenegative pattern.

The arrangement of the supporting-frame A, the drive-shaft B, and themeans for applying power thereto, as well as the arrangement of thepunches O, the punch-retaining key-rods D, the selecting-needles E, andthe levers F for connecting the selecting-needles with thepunch-retaining key-rods is quite similar to that shown and described inPatent No. 556,775, granted to Hoyle, March 21,

1896, and in Patent No. 304,864, granted to V. Boyle and J. Royle, Jr.,September 9, 18811,

and a particular description of the same is omitted from the presentcase.

Our present invention comprises a card- 'race and a pattern-cardcylinder which for purposes of explanation will be distingished from apattern-card cylinder at the opposite end of the machine as apositive-patterncard cylinder, the card-race and chain of the cards onthe positive-pattern-card cylinder being made adjustable laterally ofthe machine in order to shift the pattern-cards one or more rows ofholes laterally, so as to repeat more or less of the width of thepattern, as may be desired,- the positive-patterncard cylinder being ofspecial construction to adapt it to this lateral adjustment.

Our invention further comprises a pattern-' card cylinder which we termthe negativepattern-card cylinder, mounted at the oppo site end of themachine from the positive-pattern-card cylinder and operated by acylinder carriage common to the two pattern-card cylinders, apattern-card-cylinder feed mechanism,both direct and reverse, for eachofthe said pattern-cardcylinde rs and actuated from the commondrive-shaft, one or both of the feed mechanisms being of specialconstruction to vary the intervals of feed, means for beginningthereciprocating movements of the pattern-cylinder carriage at dilferentintervals with respect to the feed of the chain of pattern-cards to bepunched, means for varying the intervals between the different steps offeed of the chain of cards to he punched, means for throwing out ofaction one or more .of the selecting-needles at pleasure, and certaindetails of structure in connection with the above-stated features forinsuring the practical operation of the parts in harmony.

The detailed explanation of the several parts will follow,as near as maybe,the outline hereinabove set forth.

The positive-pattern-card cylinder is denoted as a whole by G. It ismade longer than the length of a pattern-card-in the pres ent instancesufficiently long to permit the shifting of the chain of pattern-cardslater' ally a distance equal to one-half the length of a pattern-card.That portion of it which the chain of pattern-cards normally occupy ismade skeleton, being provided on each of its four sides with aperforated plate 9 for permitting the free longitudinal movement of theselected needles through its wall. The pegs for engaging the peg-holesin the chain of pattern-cards to feed the chain forward at intervals aredenoted by g and are arranged in two sets for engaging the opposite endsof the pattern-card. The pegs g are attached to dovetailed strips gextending longitudinally of the cylinder and located at the middle ofeach side of the cylinder, the said dovetailed strips being adapted toslide longitudinall y along the dovetailed groovesgiformed in the sidesof the cylinder. The several dovetailed strips g are arranged to beoperated simultaneously by means of a band g, which encircles thecylinder and is fixed to each of the said dovetailed strips. The saidstrips may be-secured in their adjustment longitudinally along thecylinders by means of screws g adapted to engage one of a series ofperforations 9 formed in the bottom of the groove 9 in which thedovetailed strip slides. In addition to the simultaneous adjustment ofthe two sets of pegs longitudinally along the cylinder the individualpegs g have a limited adjustment independent of the strip to which theyare secured by means of thin strips 9 seated in shallow recesses in theunder side of the dovetailed strips 9 and carrying at one end the peg g,(see Fig. 14,) which extends up through an elongated opening 9 inthe'dovetailed strip, the: thin pegcarrying strip g being itself securedto the band 9 by a set-screw g ,which passes through the band g andthrough an intermediate spacing-block g fixed to the peg-carrying strip9 and having a limited longitudinal movement in an opening 9 in the faceof the dovetailed strip g In like manner the pegs g at the opposite endof the card have a limited adjustment toward and away from the center,the peg itself in this instance being screwed directly into the strip inthe bottom of the dovetailed strip and clamping it and the peg tightlyto the dovetailed strip at the desired adjustment. I

' The above-described structure of the posi tivepattern-card cylinderadmits of adjustingthe sets of pegs with great accuracy to suit theexact distance of the peg-holes in the opposite ends of the. cards andat the same time admits of adj usting the sets of pegs simultaneouslyalong the cylinder, so as to cause the chain of pattern-cards to omitone or more needles at the right up to onehalf the length of apattern-card. It is to be understood,t'urther,that this limitation isnot absolute; but it is at the present time all that is found necessaryas it may in the future be found desirable to shiftthe chain ofpattern-cards a greater or lesser distance than that herein providedfor.

To correspond with the shifting of the chain of pattern-cards along thepositive-patterncard cylinder G, the card-race H itself, of well-knownor approved form, is made adjustable laterally of the machine by meansof an elongated slot it, (see Fig. 3,) formed in its end plate adjacentto the machine and provided with a bolt or set-screw h for holding itfirmly to the machine in its lateral adjustment.

The negative-pattern-card cylinder is denoted by G and is in itsstructure and arrangementquite similar to that shown and described inconnection with the Letters Patent hereinabove referred to. It ismounted on the same carriage which carries the positive-pattern-cardcylinder G, at the opposite end thereof, and there is provided at therear end of the machine, to work in conjunction with the cylinder G, acard-race H of wellknown and approved form. This card-race 11 may beremoved from the machine when the negative cylinder G is not used forcontrolling the punches; but the cylinders Gand G have a doublefunction, each being used when the other is carrying the chain ofpattern-cards for controlling the punching, as a means for throwing theselecting-needles all back into normal position. This is accomplished bysimply hanging a blank card on the face of that cylinder not carryingthe pattern-cards which is adjacent to the needies, so that when thecarriage moves in a direction to carry the cylinder which is carryingthe chain of pattern-cards away from the needles the opposite cylinderwill bring this blank card into engagement with the bank of needles andset them all in position to be acted upon by the cylinder which is forthe time being employed to carry the patterncards. Needle-boards e e areprovided, one at each of the opposite ends of the bank ofselecting-needles.

\Ve have shown in detail in Fig. 11 means for centering and holding thepattern-card cylinder as it approaches the needles to operate upon themfor the purpose of keying certain of the punches, the said centering andholding mechanism consisting of a disk I, fixed to rotate with thepattern-card cylinder and provided with V-shaped notches 2' in itsperiphery, one notch for each face of the cylinder, anda spring-actuatedplunger i,

fixed on the frame of the machine and provided with a tapered nose '9,adapted to enter the V-shaped notch i which faces it, and by itsengagement with the one or the other of the walls of the notch givingthe cylinder that slight rotary motion (in case it is not in the exactposition to engage the needles) to put it into the exact positionrequired.

The tension device for regulating the movement of the selectingmeedlesis indicated at J and is of the same type as that shown and described inLetters Patent No. 556,775, hereinabove referred to.

The carriage K for supporting and reciprocating the cylinders G G isextended in width to accommodate the extended positivepattern-cardcylinder G and is also provided at its opposite end with means forsupporting the negative-pattern card cylinder G. With these exceptionsit is constructed and mounted in a manner quite similar to that shownand described in the patent before referred to, and a detaileddescription is omitted.

The lever arm or, as in the present instance, arms 70 for reciprocatingthe carriage are fixed on a rock -shaft 70 extending transverselythrough the supporting-frame of the machine, and are connected with thecarriage by links 76'. From one end of the shaft 79 two levers k 70extend downwardly to a point between a pair of operating cam-wheels L L,mounted on a shaft Z, extending transversely across the supporting-frameand driven from the drive-shaft B by means of gear Z on the cam-wheel L,arranged to intermesh with a pinion on the drive'shaft B, (indicated at1), Figs. 2 and 3.) The cam-wheels L L are pro vided with cam-grooves ontheir faces, (indicated in dotted lines in Fig. 2,) one of them toengage a laterally-extended roller Z on the arm 70 and the other alaterally-extended roller Z on the arm 7%. The cam-wheels L and L arefastened to the rock-shaft Z by a set-screw or other well-known orapproved means which will permit them to be shifted along the shaft intoand out of engagement with the one or the other of the arms 75 as may bedesired, for the purpose of starting the reciprocating movement ofthecarriage in the One or the other direction from the central positionof its stroke, as may be desired.

For example, the cam-wheels L L being simultaneously rotated in the samedirection, when the cam L is engaged with the lever 71: it will startthe reciprocating movement of the carriage in one direction from thecentral position of its movement, and when the camwheel L, with asimilar cam-groove on its face, is engaged with the lever 741 and thecam-wheel L thrown out of engagement with the lever 7.: it will startthe reciprocating movement of the carriage in the opposite directionfrom the central position of its movement, and this will have the elfectof changing the interval between the presentation of successive cards onthe pattern-card cylinder with respect to the feed of the chain of cardsto be punched. The levers k k are made adjustable with respect to eachother by bolts 756 70 which extend through one of the levers and throughelongated curved sockets in the opposite lever, and the lovers 7c 70'are made simultaneously adjustable with respect to the connecting-arm 7tby means of a bolt 7c ,which extends through the extended head of thelever it and through an elongated curved socket in the arm 70.

, There are two sets of mechanisms for rotating the pattern-cardcylinders, one set for each cylinder. These mechanisms are substantialduplicates of one another and are both carried by the carriage K andoperated byeccentrics on the shaft Z in a manner quite similar to thatshown and described in connection with the former patent hereinabovequired.

referred to. They have, however, the following important modification,as follows: The pawl for operating the one or the other of theintermeshing gear-wheels M M, through which motion is communicated tothe patterncard cylinders to rotate them forwardly or backwardly, has anauxiliary pawl carried by it,which may be thrown into and out of actionto cause the main pawl to vary the intervals between successivemovements of the patterncard cylinder. The main pawl is denoted by N andis pivoted to the rocking lever O to be swung into engagement with theone or the other of the gear-wheels M M, as may be re- The pawl N hasattached at its side the auxiliarypawl N, (see Figs. 8, 9, and 10,)which may be thrown down into position (see- Fig. 8) to engage lateralteeth on a disk P, mounted concentric with the gear-wheel M, or may bethrown back out of position to engage the lateral teeth 1) on saidWheel. The disk P has fixed to rotate therewith aseries of guardfingerspin the present instance only half the number of guard-fingers thatthere are teeth on the disk P and on the gear-wheel M.

The teeth 12 on the disk P correspond in the present instance totheteeth on the wheel M, with which the main pawl N engages. The

guard-fingers p are so arranged that when they come opposite a tooth onthe gear-wheel M theywill hold the main pawl N out of engagement withthat tooth, so that it will work idly and will not operate thepattern-cylinder at that stroke. The result is that when the auxiliarypawl N is thrown in position to To tate the disk P, as shown in Fig. 8,it will at every alternate stroke rotate one of the guardfingerspopposite a tooth on the gear-Wheel M repeating the pattern to thatextent. WVhen' the pawlj N, with its auxiliary N, is thrown over intoengagement with the gear-wheel M, it will in like manner delay theoperation of the pattern-card cylinder in its backward movement duringone or more steps of feed,

according to the number" of guard-fingers,

with relation to the number of teeth'with which the pawl engages. On theother hand,' when the auxiliary portion N is thrown back out ofengagement with the teeth on the disk P, the pawl N will operate thegear-wheel M or the gear-wheel M at each step or stroke.'

A similar arrangement of pawls is shown in cesses p in their oppositefaces for partially. receiving the teeth on the disks and having Tensionis conveniently ap their opposite arms connected bya spring 1 by meansof which the arms are constantly pressed in a direction toward the disksP P to hold them in the position in which they may be temporarily placedby the action of the pawl N. This serves to prevent the guardfingersfrom unintentional working into position to interfere with the constantaction of the main pawl N when the auxiliary pawl is thrown out ofaction and also insures the holdin g of the guard-fingers p in theproper rela tion to the teeth on the gear-wheel to cause the main pawlto ride over the-tooth without engaging it whenever it is desired toutilize this. action. The mechanism for feeding the chain of cards to bepunched is also provided with an auxiliary pawl,which operates, inconjunction with the main pawl, toproducea result quite similar to thatproduced by the pawls hereinabove described in connection with themechanism for rotating the patterneard cylinders; but in this instancethe main.

pawl Q (see Figs. 5, 6, and 7) is made wider than the width of aratchet-tooth g on the ratchet-wheel which actuates the feed, and anauxiliary pawl Q is pivoted concentric with the main pawl Qand operatesa ratchetdisk q, mounted concentric with the ratchetwheel which actuatesthe feed and free to rotate independently of the said ratchet-wheel, thesaid ratchet-disk q being provided at in tervals withlaterally-projected teeth g in the present instance located oppositeevery jecting into the path of the main pawl Q, so that when one of theextended teeth (1 of the ratchet-disk comes opposite one of the teethpawl Q fromv engaging the ratchet-tooth, and hence the feed will bedelayed until the succeeding stroke, when the disk q will have beenmoved one step forward,thereby leaving the ratchet-tooth q free to beengaged by the main pawl Q.

By means of the changing of the intervals of feed of the chain of cardsto be punched and also the intervals of feed of the patterncards both onthe positive cylinder and upon thenegative cylinder a great variety ofvariations of the original pattern may be pro duced. This variety may bestill-fnrtheraugmented by the changing of the chain of pattern-cardslaterally on the positive-patterncard cylinder and by the change indirection of the initial movement of the carriage.

Thediagrams Figs. 21 and 22 show portions of a positive and negativecard, the one represented in Fig. 21 being punched by the punches underthe control of the chain of pattern-cards on the positive-pattern-cardcylinder G and the one represented in Fig. 22 being punched by thepunches under the control of the. same pattern-card on thenegativepattern-card cylinder G. In short, all those punches. which werethrown into action by the pattern-card on the cylinder G were thrown outof action by the same patterncard on the cylinder G, for the reason thatL the same selecting-needleswhich were thrown in one direction by thecard on the cylinder 1 G were thrown in exactly the opposite directionby the same card on the cylinder G.

For the purpose of throwing certain of the selecting-needles temporarilyout of action we provide removable needle-tips R, (see Figs. 17, 18, 19,and 20,) which are remov- I ably connected to the selecting-needles bymeans of split socket-pieces 'r, the latter being fixed permanently tothe body '1" of the j needles at one end and provided at their op:positeend with split sockets adapted to reiceive the tips R and gripthem.suffici'e'ntly tight to cause them to operate successfully inconnection with the needles and at the same 1 time admit of their beingremoved by a strong endwise pull.

Hence we do not wish to limit ourselves strictlyto the structure herein set forth 5 but What we claim i-s-- v 1.
